WHEEL ARC RADIUS

WHEEL ARC RADIUS

OBJECTIVE :

Using the european standards discussed, Calculate the wheel arc area and prove weather the car will pass the standards or not.

WHEEL ARC AREA:

It is an arc shaped cavity portion on the vehicle body where the arc shaped region. Houses the wheel with standards condition. It serves for safety of pedestrains and other cars because of the wheel is situated on the body of the vehicle. To check the radius between the fender and the wheel wether it obtained the european standard condition.

Few other standards mentioned in the Tabel:

Here, I performed with european standard condition to calculate the wheel arc radius for housing the wheel in body of the vehicle.

REQUIRED CONDITIONS:

CALCULATING THE WHEEL ARC RADIUS USING CATIA V5 :

1. As per european condition the clearence criteria 'L' for the wheel arc's radius is 10mm or greater than.
2. L's radius should meet the standard condition otherwise, its needs to change in the fender design.
3. SA, SB, SC, SD, SE are the calculating sections for measuring the clearence.
4. Measuring the distances to check weather it met condition of european standards.
5. If the design of the fender meets the condition it can be acceptable for the further process.

CONDITION OF SECTION-A IN DESIGN (SA):

CONDITION OF SECTION-B IN DESIGN (SB):

CONDITION OF SECTION-C IN DESIGN (SC):

CONDITION OF SECTION-D IN DESIGN (SD):

CONDITON OF SECTION-E IN DESIGN (SE):

CALCULATIONS AND RESULTS:

SECTIONS REQUIRED ACTUAL RESULTS

ON E.S CLEARENCE CLEARENCE

SA >10mm 9.956mm FAIL

SB >10 mm 10mm PASS

SC >10mm 0.092mm FAIL

SD >10mm 1.643mm FAIL

SE >10mm 3.307mm FAIL

1. From the table condition of section-B(SB) is can be acceptable and SA, SC, SD & SE regions are not acceptable.

2. Further the design of the fender needs to be changed so that it can obtain an european standards.
